Anybody see the episode where they dyno a LS motor and use 3 different oil pumps?
they used two HVHP pumps and one HV. I think they were all made by Melling. The HV was best by 15hp. Very surprising results. Wish they would have used a stock pump too. It would have probably been better than the HV pump.

But any of those pumps work great so what u getting at is just because its higher ull buy that one???
I saw it last night. I don't think any of those pumps would make that much pressure in a real LS2/LS3. Or at least I hope not, since I just put a Melling in my rebuild and am installing the engine next week!
Here is the various flow rates and pressures.....I'm sharing because it took me WEEKS to find this!
The HV std pressure gave the most HP on the show. When I did my cam, I reused my factory pump. I get enough pressure to keep me happy.
Same here. Did all of the work on my LS3 at about 30K. It had good oil pressure before. Nothing we did to the engine would have any effect on oil pressure. Plus, an LS oil pump isn't a really complicated piece. Not much to go wrong.
They didn't really go into it, but GM pumps apparently cavitate above above 6500 rpm. I never saw this in my shimmed (pressure spring) stock pump, but I wasn't logging extensively.
All of the Melling pumps claim to have improvements to reduce or eliminate the cavitation.
I think they did the engine masters backward, really all they did was show EXTRA flow and pressure don't help in any way. I would have been nice if they ran some OEM pumps from different engines since that is what more of us have to compare with.. You only need what you need.
Demonstrating the effects of windage...
I've watched a few episodes, and I'm actually impressed with their accuracy.
Unlike most of the other BULLSH*T motor trend TV 'reality' shows.

Did you guys catch the episode swapping just oil pans for horsepower?
They found a $1,000 cast aluminum one and they gained 30hp
They said that price was ridiculous but when they saw how it performed they said if they had the cash in a budget, they would use one.

YEP - It's about keeping oil off the spinning crank, while still supplying the oil pump with all the oil it can pump.
Fairly easy to do with a deep sump pan - not so easy when you are doing a road race set-up, and you want the engine down low in the chassis for the low CG, while maintaining some ground clearance...
Nowanker, I agree this is the ONLY show of this type that isn't just an infomercial. They never promote brands, they just spell out what they are doing and throw it on the dyno. They aren't all interesting topics but tons of relevant shows by those guys.
I was n the 'business' for 40 years, and I've seen all kinds of stupidity and bullsh*t come and go.
It takes a lot to impress me...
I watched some episodes, trying to spot the baloney.
I was impressed instead.

Why not? If all 3 flow enough oil, and one of the 3 is better by 15hp (which is hard to believe, imho!), that's the one I'd want. 15hp seems a bit extreme, but I haven't seen the test, or guidelines.
